This flag marks whether a resource policy is a global, systemwide, policy or a local one scoped to a specific resource user type, and it is locked in permanently the moment the policy is created. Because this cannot be changed later, an admin who creates a policy with the wrong scope has to delete and recreate it rather than toggle this flag, which matters when planning a policy's intended reach up front. A policy created with this set to true to cover systemwide CPU thresholds can never later be narrowed to apply only to, say, voice-related processes -- it would need to be deleted and rebuilt as a local policy instead.
